HINGE.

Application filedafieptem her -7, 1922. Serial No. 586,627.

Our present invention particularly pertain-s .toa hingeof the frictionallock type. with object o'f our invention is to. provide a constructionin hinges whereby movement c of theleaveszofrthe hingerrelative to eachotherwill be yieldably. opposed so, that a closure carried on hingesembodying the mvention may be frict-ionally held against tree movement:in either. direction, and

no swinging oi the closure. from any position yicldably resisted. i y

Another object is to provide a1 means whereby an ordinaryxlooseipinhinge maybe converted into; airictional lock hinge with J butslightchange of the original hlnge structure. I a

. NVith the.iforegoingobjccts. in 'VIBW, together with suchotherobjeclts andradvaln tages aswmaysubsequently appear, our 1n-\ention consists of the parts and the comb1 nation, arrangement andCQDStIYllCtlOIL- of parts hereinafter.described and claimed andillustrated in ithc accompanying drawing, m -\v-hich:-

r i 1 Figures 1,2 and 3xare views showing the parts of the hingedisassembled; Fig-1 being a view in elevation of one of the hingeleatmembers, Fig. 2. being a view in elevation oi the otherhingeleaf.inemben with the removable pivot pin, and Fig 3 being aperspective" view of a: ratchet Cl1SC attachment .tozbe embodied in theimage.

4. is a view in elevation of one of the hinge leaf members, showing themanner of applying the ratchet disc.

Fig. 5 is a View in elevation showing the hinge as assembled.

Fig. 6 is a detail in section as seen on the line 6-6 of Fig. 5.

Fig. 7 is a detail in section as seen on the line 7-7 of Fig. 6.

Fig. 8 is a detail in section as seen on the line 8-8 of Fig. 1.

Referring to the drawings, more spec1fically, 8 and 9 indicate thestraps or leaves of the hinge which are formed with perforatedprojections or knuckles 10 and 11-11', respectively, and which knucklesare adapted to be pivotally connected by a pintle or pin 12 in such amanner that the leaves may have articulate movement relative to eachother, as is common in hinge construction.

In the hinge here shown the knuckle 10 on the leaf 8 is interposedbetween a pair of spaced knuckles 1111 on the leaf 9 andpivotallycarried on the latter by the pin 12, which pin passesthroughthe upper knuckle 11, through the knuckle 110, and engagesthelOWs-rknuckle 11; the pin 12 be ing preferably loose and being demountable topermitready connection and separation of the hingeleaves.

In carrying. out our invention the knuckle 10 is formedwith a transverseslot ,13 intermediate its ends, which slot extends into the plateportion 14 0.? the hinge leaf a short plate and riveted inplace as shownin Fig. 8.

v .A demountz'ible circular ratchet disc 17 is provided, which disoisformed with transverse serrations on its perimeter and is adapted ts .beinserted 'in the slot 1E1. Acen- ,tral opening. 18 is, formed in thediskadapted to register with theopening the knuckle 10 and through which:opening the 19111 12 '18 designed-Etc extend The disc 17 is of adiameter, exceeding that of the knuckle 10 and, is formed with atransverse channel-.19 on one side thereof, adapted to receive the edgeof the plate portion 20 of the hinge leaf 9 as particularly shown inFig. 6, whereby the disc is engaged with the leaf 9, and held againstrotation relative thereto.

In asscmblying the hinge the disc 17v is mounted on the leaf 9intermediate the knuckles 11-11, as shown in Fig. 4:, whereupon theknuckle 10 is placed between the knuckles 11-11 with the disc arrangedin the slot 13.

The pin 12 is then inserted in place and in passing through the discserves in conjunction with the notch 19 to hold the disc firmly inplace.

When the hinge is assembled, as shown in Fig. 5, the serrated perimeterthereof is located concentric with the axis of the pivot pin 12, and theserrations of the disk are engaged by the spring 15 which bears undertension against the edge of the disc and normally extends into thetransverse recesses 21 formed by the serrations on the disc in suchfashion so as to frictionally lock the leaves 8 and 9 against freearticulate movement The wire 15 is circular in cross section and thercesses 21 are arcuate to conform to the curved periphery of the.spring, which construction permits the spring riding from one recess toanother on suflicientpressure being brought to bear on the leaf memberstending to impart articulate movement thereto. The spring is of suchtension as to cooperate with the serrated disc, and form a ratchet-likedetent.

From the foregoing it will be seen that we have provided a constructionwhereby an ordinary leaf hinge may be converted into a frictional lockhinge, in which articulate movement of the hinge leaves will beyieldably opposed in either direction.

A hinge constructed in accordance with our invention is particularlyapplicable for use on casement windows to inhibit free swinging movementof the window,-and permits the window being disposed and held in anopen, closed, or partially open position, without the use of fastenersother than that afforded by the hinge.

It will also be seen that by constructing the frictional locking elementof the hinge as herein set forth, the hinge may be manufactured with thefrictional locking feature at a cost slightly greater than that of theordinary hinge not so equipped, and that by forming the serrated disk sothat it is demountable the disk may be readily removed and replacedwhich permits its being renewed in event the serrations becomeexcessively worn.

We claim;

1. In a hinge, a pair of leaf members formed with alined knuckles, apivot pin connecting said knuckles, a disc arranged between adjacentsaid knuckles having a serrated edge, said disc being engaged by saidpivot pin and held against movement relative to one of the leaf members,and a spring wire carried by the other leaf member frictionally engagingthe serrations on said disc and adapted to slide successively over theserrations of said disc on articulate movement of said leaf members ineither direction.

2. In a hinge, a leaf member formed with a knuckle having a transverseslot extending through the knuckle, a spring member on said leafextending transversely of said slot, at second leaf member having spacedknuckles positioned astride the knuckle on the other leaf member, a discarranged in said slot having a serrated edge engaged directly by saidspring and held against movement relative to the last named leaf member,and a pivot pin connecting the knuckles of the leaf members and passingthrough said disc.

EMA hinge, comprising a leaf member formed with a. knuckle and having atransverse slot extending through said knuckle, a spring wire carried bysaid leaf member having its ends affixed thereto, said spring wirearranged to extend transversely across the inner end portion of saidslot, a disc formed with a serrated edge, said disc arranged in saidslot with its serrated edge engaged by said spring wire, said disc beingformed with a notch a second leaf member having knuckles arrangedastride the knuckle on the other leaf member, said second leaf memberengaging the notch in said disc, and a pivot pin connecting the knuckleson said leaf members and extending through said disc.
